GEAR-SHIFTING-LEVER LOCK.

Specification of Letters Patent.

Patented May 13, 1913.

Application filed May 23, 1912. Serial No. 699,185.

To all w/Z-om it may concern:

Beit known that I, O'r'ro W. HAHN, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Gear-Shifting-Lever Look, ofwhich 'the following is a specification" in such fulland clear terms aswill enable those I skilled in the art to construct and use the same.

This invention relates to a locking device for the gearshift lever of anautomobile and its object is to produce a strong lock which is easilyoperated and which can be applied to the gear lever with the minimum oflabor.

It will be understood by those skilled in the art that the gear changesof an automobile are usually accomplished by means of a lever workingthrough a slotted arm. This lock comprises a slidable bolt securedthereto which bo-lt can be locked in either one of two positions, in oneof which it offers an obstruction to the movement of the gear shiftinglever and prevents the car from being operated.

In the drawings in which the same numeral of reference is applied to thesame portion throughout the several views, Figure 1 is a side elevationof a portion of the gear shifting lever having this look appliedthereto, Fig. 2 is a vertical sectional view of the lock and plate forsecuring the same to the lever, Fig. 3 is a view in elevation of thelock and plate for securing the same to the lever looking from the sideto which it is fastened to the lever, Fig. 4 is a side elevation of thelock with the plate for securing the same to the gear shifting leverremoved, Fig. 5 is a side elevation of a portion of the gear shiftinglever and the slotted plate through which the lever moves to change thegears, and Fig. 6 is a sectional view of the slotted plate and a portionof the gear shifting lever showing the relation of the lock to the leverand slotted plate.

The numeral 1 represents the gear shift-- ing lever and 2 represents aplate which is secured to the gear shifting lever by means of suitablescrews 3. This platev has two notches el and 5 therein, which notchesafford the means for holding the slidablebolt 6 in the desiredadjustment. The slidable bolt 6 has a recess therein at 7 and a deeperrecess at 8. In the recess 7 a lock 9 is pivoted on a pin 10, a spring11 holding said lock normally in the position shown in Fig.

2. The upper endof the lock 9 has an arm 12, which arm contacts with thearm 13 .on

the bottom of the lock barrel 1 1. The lock .barrel 1 1 has anes'cutcheon 15 through which the key is inserted in a well known mannerfor the rotation of the arm 13.

VVhen in use a screw. 16 is run through the the bolt from beinginadvertently lifted too high on the plate 2, (note Fig. 6).

An automobile body is shown at 1'? and arms 18 are shown supporting theareshaped plates 19, 20 and 21, which form a path for the lever 1. Itwill be observed that the lever can move through the slot formed by theplates 20 and 21 and 19 and 21 only when no wider than those slots.However, when it is desired to lock the lever the bolt 6 is moved downinto the position shown in Fig. 6 and thus efiectually prevents thelever from being shifted out of the center position.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States, is as follows:

1. A look for automobiles comprising in combination with a stationaryquadrant and a lever movable relative thereto, of a plate having guidesat the sides thereof secured on said lever, a bolt covering said plateand slidable thereover and covering its securing means, a locking membercarried by' said slidable bolt, and means to secure the bolt in theretracted or the extended position, substantially as described.

2. In a lock for automobiles, the combination with a change gear lever,of a plate having guides at the sides thereof, means to secure saidplate to said lever, a slidable bolt carried by and slidable over saidplate and covering its securing means, and a pivoted latch carried bythe slidable bolt and adapted to cooperate with means upon the plate tohold the bolt either in the extended or the retracted position,substantially as described.

3. In a lock for automobiles, the combination with a change gear leverand a slotted quadrant through which said change gear lever passes, of aplate secured to said lever adjacent the slottedquadrant, a recessedbolt slidable on said plate and covering the same, a pivoted latchcarried by said slidable bolt and operating within said recess forsecuring it in the extended or the retracted position, and key-operatedmechanism for re leasing the latch at will, substantially as described.

4. A look for automobiles comprising in combination With change gearlevers and a slotted quadrant through which said levers move, of a guideplate provided with detents secured to the lever adjacent the slots insaid quadrant, means to secure said guide plate to the lever, a recessedslidable bolt carried by said plate and having longisame, means tosecure said plate to said lever, a locking member carried by theslidable bolt and operating Within the recess and cooperating with saiddetents in said plate to hold the bolt in the retracted or extendedposition, and amechanism located in the- OTTO W.
